I am not sure if I was looking at it properly, but as of writing this, post count is: 1,464,644. I think I may have seen a larger figure few days back, something like, 15.....

I know that posts get closed, but there is always a reference to those and we can view them. Is there some kind of mechanisms that completely removes incorrect posts and hence a decrease in post count.

Certain posts which are poorly framed, and/or offtopic tend to be deleted by Moderators and/or High-rep users. In addition, there are couple of background processes which delete old posts meeting certain criteria:

less than (question age in days * 1.5) views

0 score or lower

no answers

1 comment or less

asked more than 365 days ago

In addition unanswered, negatively voted questions with zero answers are also deleted after 30 days.
